Enhancement Of New Radio PUSCH For URLLC In Mobile Communications

摘要

Various examples and schemes pertaining to enhancement of New Radio (NR) physical uplink shared channel (PUSCH) for ultra-reliable low-latency communication (URLLC) in mobile communications are described. An apparatus determines whether to apply a cyclic delay diversity (CDD) scheme for a PUSCH transmission. The apparatus performs the PUSCH transmission to a network node of a wireless network with the CDD scheme applied responsive to determining that the CDD scheme is to be applied. Optionally, the apparatus receives a signaling from the network node indicating information related to mini-slot repetition such that the apparatus performs the PUSCH transmission with at least one symbol repeated in multiple mini-slots within a slot. Optionally, the apparatus also performs a transport block size (TBS) calculation for the PUSCH transmission with an assumption of no demodulation reference signal (DMRS) in the TBS calculation.
